The AIx' internal value is the result of the following equation:
For instance: AIx=5 V, OFFSET=-70 % and Gain=1.000:
AIx'=-2 V means that the motor will rotate in the reverse direction with a reference in module equal to 2 V, provided
that the AIx function is "Speed Reference". For the AIx function "Maximum Torque Current", negative values are
clipped at 0.0 %.
For the filter parameters (P0235, P0240, P0245 and P0250), the adjusted value corresponds to the RC constant
used for filtering the signal read at the input.
P0233 – ai1 Signal type
P0243 – ai3 Signal type
Adjustable 0 = 0 to 10 V/20 mA
Range: 1 = 4 to 20 mA
2 = 10 V/20 mA to 0
3 = 20 to 4 mA
P0238 – ai2 Signal type
P0248 – ai4 Signal type
Adjustable 0 = 0 to 10 V/20 mA
Range: 1 = 4 to 20 mA
2 = 10 V/20 mA to 0
3 = 20 to 4 mA
4 = –10 V to +10 V

via HMI:
Description:
These parameters configure the signal type (if it is current or voltage) that will be read at each analog input, as well
as its range. Refer to the tables 13.1 and 13.2 for more details on this configuration.
